Problem
The Igf2 gene is maternally imprinted. People who have a deletion in one chromosome in the location of the Igf2 gene will be short in stature if the other chromosome is imprinted. "I" represents the normal Igf2 allele and "i" represents a deletion allele. A * indicates the imprinted (methylated) chromosome. Katy (I*I) and Luke (I*i) have a daughter, Carolyn, who has short stature. What gametes can Carolyn make? Include methylation in your answer.
